American Law Reports (A.L.R.) are a set of books in 7 series (A.L.R. 1st through 6th, plus A.L.R. Federal), which contain in-depth articles (called "annotations") on specific legal issues. A.L.R.s are a secondary source - they point you to primary law on your topic, hopefully in your jurisdiction. The articles are written to be more practice oriented than scholarly, and were usually fairly "cutting edge" when first published. A.L.R.s are a good place to begin your research if you are starting from scratch.
To find a relevant annotation look to the end of this set for a series of books titled "A.L.R. Index". This index will guide you to annotations in A.L.R. series 3rd through 6th, plus the Federal A.L.R.s. Use terms which describe your issue (who/what/how) to find citations to specific annotations.
( A.L.R. 2nd and 1st are older and use a different finding method, please see a reference librarian for help using these older materials.)
The citation format the index uses will be in the form
Title [volume] A.L.R.[third through 6th or federal] page number
or for example:
Landlord's liability for injury or death due to defects in areas of building (other than stairways) used in common by tenants, 65 A.L.R.3rd 14
..would mean, "Volume 65 of the A.L.R.3rd, page 14"
Most A.L.R.s are laid out in a standard format to help the user quickly find information:
Remember, annotations are not primary authority. But if you have to cite to one, the general format is:
Allan E. Korpela, Annotation, Landlord's liability for injury or death due to defects in areas of building (other than stairways) used in common by tenants, 65 A.L.R.3rd 14 (1975).
Note - the date you list is the original publication date of the annotation, not the date of the pocket part.
Please consult your A.L.W.D. or Bluebook for more exact citation rules.
