With that in mind, let’s look at 105 CMR 125.004. Let’s say you’d like to see all the changes that regulation has gone through since 2015. We’ll trace the history of this regulation together.
To start, we’ll need to go to the Cumulative Tables. The Cumulative Tables, sometimes called “indexes,” are published in the final Massachusetts Register of each calendar year. The cumulative tables start in 1976 and continue through to the present. These tables document all regulation filings, including amendments, new regulations, and emergency regulations, published in the Register during that year.
You’ll find the Cumulative Tables in our digital repository. We also maintain a binder of Cumulative Tables from 1978 to the present, available in our Reading Room alongside the CMR. If you don’t know when a regulation was first added or when it was amended, you should begin by looking at the earliest Cumulative Table and work forward through each year. This helps you create a timeline of the regulation’s history.
As we mentioned, we want to see all the changes that 105 CMR 125.004 has gone through since 2015. We’ll start by looking at the Cumulative Tables file that includes 2015, using the Tables found in our digital repository.
- Left-hand side: Agency title numbers (also called “digit title numbers”) in bold, with their chapter numbers listed beneath.
- Right-hand side: Two columns showing
- The Register issue number where the regulation was published, and
- The effective date of the amendment or filing
For example, a page from the 2014-2025 year-end Cumulative Table shows there were amendments to 105 CMR during that time period. The first amendment for 105 CMR 125 appeared on 2/24/17. By noting the Register issue number (1333), you’ll know exactly where to look to find the full text of the change.
Hint: look for the Settings section on the left side of your screen. Set the “Sort By” to “Z→A.” This will sort the Registers from newest to oldest, making it easier for you to find the specific Register you need. In our example, you’ll want to look at Register 1201 through 1400. Next you’ll search for Register 1333 to see if sub-section .004 is listed.
In our example, 105 CMR 125 was updated on the following dates, focusing only on the changes that have occurred since 2015 :
2/24/17 (Register 1333)
From there, we’d look in the Registers to see if sub-section .004 is listed. You can search for a specific Register by searching for “no. XXXX” in the Search bar above the list of Items. Here are our search results when we search for Register 1333 using that format:
