Video Source Book - get new edition every year, 2 books
Bowker Video Directory - get new ediction every year, 4 books
Leonard Maltin's Guide - get new one each year, 1 Trade PB
Video Guide - I think by Martin, with an additional author, - get new one each year, 1 Trade PB
These are all kept at our public service desk and I encourage their use by the public and staff. The more popular press books - Maltin and Martin guides - get the most use. I switched these to trade paperbacks from mass market Pb's when I noticed the trouble some people had with the smaller print. My ILL department plus desk staff use the Bowker and Video Source Book more than the public. However, they are good sources for people to use to locate videos they wish to purchase, especially if they do not like the Internet.
I thought about dropping the Bowker Guide this year but my ILL staff told me they use it about three to four times a month to locate videos for the public. I decided to keep it another year.
Other resources I have for both the public and staff to use are not S.O. purchases but very useful for a public library to have available. They are more popular videos guides: NYT Best Children's Videos, Movie Mom's Guide to Family Movies, Family Guide to Classic Movies, and Videohound World Cinema.
Hope this helps,
