Legal Research Resources

This resource guide is designed to lead researchers to primary Maryland and Baltimore County legal sources held by the Law Library or freely accessible online. However, it is not an exhaustive list of resources and is not meant as legal advice. The Law Library is not responsible for the information linked to or the utilization thereof.

While the Law Library provides links to legal resources online, the courts may or may not accept material found online as evidence. Section 10, subtitle 200 of the Courts and Judicial Proceedings article of the Maryland law should be reviewed before submitting online material in a case. If there are any questions about what is or is not admissible, check with an attorney.

Maryland Laws, Regulations and Court Opinions


Annotated Code of Maryland—The Law Library has an almost complete collection of the 1957 Code in print.

The Maryland Archives Online—Provides access to the historical session laws

General Assembly—The Maryland General Assembly offers many useful resources for legal researchers including information on committees, finding legislature members by address, a variety of publications, hearing videos, links to municipal charters, fiscal and policy notes, and access to order bills from 1996 forward.

Executive Orders and Regulations

Executive Orders—From time to time the Governor issues orders that have the effect of law. These Executive Orders are available on the Governor's website.

COMAR—The Code of Maryland Regulations (COMAR) is the compilation of regulations "promulgated" or created by state agencies. The Law Library holds only the most current version of the COMAR in print. Note: the contents of the Maryland Register and the Code of Maryland Regulations shall be judicially noticed from the official text of those publications. (Courts and Judicial Proceedings Article, §10-203(a)(2), Code of Maryland.)

Maryland Register—The Division of State Documents provides online access to the Maryland Register. The Register is published every two weeks and the six most recent issues can be viewed online. The Register is a temporary supplement to COMAR and publishes other public interest documents. The entire collection is available at the Baltimore County Law Library.

Court Opinions and Forms

Opinions of Maryland's Appellate Courts—The Law Library holds Court of Appeals case opinions in print starting from 1658 and Court of Special Appeals print opinions beginning with 1967. Opinions dating back to 1995 may be searched on the state's Judiciary Appellate Opinions page. It is also possible to search for case law from 1950 forward via Google Scholar.

Circuit and District Court Opinions—These opinions are not searchable and hold no precedential value.

Forms—The District Court tends to be more form driven with official fill-in-the-blank forms. The Circuit Court is more freeform with the majority of official forms relating to family law matters such as divorce, guardianship, etc. If someone needs a form for Circuit Court for which there is nothing available online, then it is possible to utilize the resources within the Law Library to get some idea of the wording to use when creating a form from scratch.  

Publications—Various publications from the judiciary.

Baltimore County Laws and Regulations

Baltimore County Law—Baltimore County laws may be found in the Baltimore County Code or the County Council Bills. The Law Library holds some older versions of these resources in print.

COBAR—The Code of Baltimore County Regulations is currently only found online.

Board of Appeals—Recent decisions of the Baltimore County Board of Appeals are available online.

Zoning Regulations—The current Baltimore County Zoning Regulations can be viewed online. The Law Library also holds select previous versions of the County's zoning regulations.

Building Codes—Parts of the current Baltimore County Building Code can be viewed online. The Law Library provides access to some historical versions of the code in print. Since the 1970s the County's Building Code consists of two components: a bill of adoption and external resources. Every three years the County usually passes a bill that adopts an external resource as the County's Building Code. This bill of adoption also contains various changes to that adopted resource.
