What is here

Delaware: the Delaware Administrative Code as the Registrar of Regulations' site (regulations.delaware.gov) showed each regulation's page on 2026-10-21, saved one page at a time in a browser by GLO's desktop session and read by machine: GLO's reading of the web pages, not the Authenticated PDF Version the site marks as the authenticated text. 755 of the 1,118 regulation pages the site's title pages list are served, from 20 titles, each a whole regulation, read alike by two readers with no shared code and checked against its authenticated PDF word for word as a multiset: up to three words (or 1 in 5,000) without a digit may still differ, none with a digit, and word order is not compared. Release 2 (2026-10-21) adds sections: 625 of the 755 regulations are split into 4,804 sections, each a slice of the whole regulation's text from its own head ("1.0") to the line before the next, the same words; 130 are served whole only, by the first test their split failed: no section head (108), section heads not in the order 1.0, 2.0, 3.0 ... (20), a line inside a section numbered as another section (2). Release 3 (2026-10-21) adds 104 of the 171 pages held for a table, so 859 of the 1,118 are served: each table row is one line, its cells separated by " | " (GLO's mark, not the page's), an empty cell keeping its place; in a row of two or more cells a cell's own line breaks are joined by a space. Their rows were checked against the browser's copied text (every word in order and where each cell ends) and their words against the authenticated PDF as above, which does not check the rows; 10 drawn pages were read by hand against the PDF's printed tables; they are not split into sections. Release 4 (2026-10-21) adds 8 of the 22 pages held only for underlined words, so 867 of the 1,118 are served: on each, every underlined span is a heading, an address, a table heading row, a title or an e-mail address, or the citation signal "et seq", which GLO read as formatting, not as words marked inserted; the text does not show underlining and the field underlined lists the 15 spans as printed. That is GLO's reading of the web page, not the Registrar's; the authenticated PDF is the check. They are not split into sections. 251 pages are held, each by name with its reasons (counted once, by the first): underlined words on a page that also carries another held class (36), words that differ from the authenticated PDF (34), a table on a page that also carries another held class (33), a table with a merged cell (30), a page that does not print its own regulation number as its line (27), struck-through words (26), superscript or subscript (21), a word with a digit that differs from the authenticated PDF, or a remainder too long to rule one out (20), an image (8), underlined words inside a sentence, the shape of words an amendment marks as inserted (5), an underlined operand in a formula, where plain text would print another formula (4), a whole numbered provision or definition underlined, the shape of inserted text (3), no authenticated PDF to check against (2), an underlined form blank, which plain text drops (1), a two-column block the text runs together line by line, found in the hand read (1). Each regulation carries its page's address and its PDF's address; the history lines in its text ("21 DE Reg. 501 (12/01/17)") are the Register of Regulations' citations as the page prints them. The key ("10 DE Admin. Code 101") is GLO's form of the usual citation from the page's address. The served regulations were checked by hand on 20 drawn regulations against the saved page and the PDF, so a fault rarer than about 1 in 7 regulations could remain unseen. Nothing here says a regulation is current or in force; check the authenticated PDF before relying on it.
Release 1: 755 whole regulations from 20 titles, copied on October 21, 2026. Release 2 (October 21, 2026): 625 of them can also be fetched section by section (4,804 sections); 130 are served whole only. Release 3 (October 21, 2026): 104 pages with tables, each table row on one line. Release 4 (October 21, 2026): 8 pages with underlined words, the words listed.
Of the 1,118 regulation pages the site lists, 251 are held and not shown, each with its reasons: mainly underlined words (49), words that differ from the authenticated PDF (34), a table on a page that also has another held feature (33), a table with a merged cell (30). A held page comes back as held, with its reasons and no text. Held is not absent.
The site marks each regulation’s PDF as its Authenticated PDF Version. What is shown here is our reading of the web page, checked against that PDF. Each regulation carries the PDF’s address.
A whole regulation comes with its sections, notes and history lines (“21 DE Reg. 501 (12/01/17)”) as the page prints them. A section is a slice of that same text, from its own head (1.0) to the line before the next head: the same words, nothing read again.
On a table page (Release 3), each row of a table is one line, its cells separated by “ | ”. That mark is ours, not the page’s. An empty cell keeps its place, so a value never slides into the next column. Table pages are not split into sections.
On a Release 4 page, the page underlines some words that our text does not show as underlined. Those words are listed beside the text. We read each one as formatting (a heading, an address, a table heading, a title, an e-mail address or the signal “et seq”), not as words an amendment marks as added. That is our reading, not the Registrar’s; the authenticated PDF is the check. Release 4 pages are not split into sections.
Look a regulation up as 10 DE Admin. Code 101 (title 10, regulation 101). A section form such as 10 DE Admin. Code 101-1.0 returns that section when the regulation is split, and the whole regulation with a note when it is not. 10 DE Admin. Code lists the regulations of title 10: shown and held. A long regulation comes back in pages, and nothing is cut.

How we checked it

Two separate readers, written with no shared code, read every page: one the page’s HTML, one the text the browser copied. A regulation is shown only where both read the same words in the same order.
Each shown regulation’s words were checked against its authenticated PDF. Up to three words (or 1 in 5,000) may still differ, and none of them may hold a digit. Word order is not compared.
A page is held when it carries a table, an image, struck-through or underlined words, superscript or subscript, when its words and the PDF’s differ beyond that, when it shows no PDF, or when it does not print its own regulation number as its line.
Before release, we drew 20 shown regulations at random and read each one against the saved page and the PDF: its heading, its first and last lines and its whole text against the page. All 20 matched.
For Release 3, a third reader read each table row by row from the page’s HTML, and a check confirmed that its rows hold exactly the words of the browser’s copied text, in the same order, with every cell ending where the copied text breaks its line. The words were checked against the authenticated PDF as above; that check counts words, so it does not check the rows. 10 drawn table pages were read by hand against the PDF’s printed tables. All 10 matched.
For Release 4, a rule written before it ran held a page if any underline marks part of a formula, a form’s blank, a whole numbered provision or definition, or words inside a sentence, since those can be words an amendment added. 8 of the 22 pages held only for underlining passed; the underlined words on each were read by hand in their lines. One more page was held after that read, because its two-column signature block runs together in the text.
For Release 2, a check confirmed that every section is exactly its part of the whole regulation’s text, and that the sections, joined back with any text before the first, give back the whole regulation character for character. 20 drawn sections were read by hand for where each starts and ends.
One AI system wrote the readers, ran every check and made every reading and ruling, with no second reader.

What it can't tell you

Whether a regulation is in force, valid or current, or is good law.
When a regulation took effect. The history lines are the Register’s citations as printed; the date shown is when the page was saved.
What the held pages say, or a difference of up to three words (none with a digit), or a moved word, between a shown page and its PDF.
Whether a table’s rows are grouped as the agency meant, beyond what the page’s own markup records.
Whether an underlined word on a Release 4 page, which we read as formatting, was in fact marked as added by an amendment.
Whether anything changed after the pages were saved.

Known gaps

251 regulation pages are held, not shown; the largest group is pages with underlined words (49, of them 13 underlining words that could have been added by an amendment, a formula part or a form blank). 34 pages with tables are still held: 30 for a merged cell, the rest for another feature as well.
130 regulations are served whole only, and their sections cannot be fetched one by one: 108 print no section heads, 20 have heads out of order, 2 have a line numbered as another section.
The split reads only heads printed as 1.0, 2.0 and so on. A head printed another way stays inside the section before it.
Bold, italics, underlining, indents and the layout of the page are not kept; the text is the page’s words, one printed line per line (a table, one row per line). In a table cell that holds more than one line, those lines are joined by a space.
The regulations were read by machine and checked by hand on 20 drawn regulations, so a fault rarer than about 1 in 7 regulations could remain unseen.
Keyword search reads only the shown regulations, table pages included. Held pages have no text here and never match.

Notes you may see on an entry

A held page: “GLO holds this regulation page and does not show its text, because its two readers, the PDF check or the release check did not clear it. Its reasons are listed by name.”
A section asked for: “When the regulation is split, the section comes back alone, a slice of the whole text. When it is served whole only, or is a table page or a Release 4 page, the whole regulation is shown, with a note naming why.”
A regulation not in this copy: “Not in this copy of Delaware’s regulations, neither shown nor held by number. That never means the regulation does not exist.”
