Designed for Collectors
We all collect something, whether it's stamps, movies, games, music, books or wine. Librarian Pro brings sophistication and class to managing your collection! Browse all of your items at a glance on a virtual bookshelf, in a list, or in cover flow.
Item artwork and information is easily and automatically downloaded from the web. Even track which items you have lent out to friends; or, for small businesses, go as far as recording late fees and due dates.
This system keeps track of all previous data you've entered and will offer suggestions as you type!
View a summary of all of your library items at once. Viewing charts that outline the total value of items in your library, genres, actors, musicians, and literally any other value you've entered!
With as little as a barcode or item title, Librarian Pro can scour the web and find all matching items and fill in the missing details. From cover artwork to the list of tracks on an album or even the full list of cast in a movie.
Complete Inventory Control
If you are managing a full inventory of items for sale on eBay, or using Librarian Pro to track which friend borrowed which movies, the power-user features in Librarian Pro will make your life a breeze.
Taking full advantage of optical recognition technology, use your web cam or physical barcode scanner to add items to your library or manage inventory. Mark items as lent out to specific users, track in your computer's calendar, automatically send e-mails or display alerts. Even manage late fees and due dates.

I recently had a house fire, and Librarian Pro helped me figure out what I had lost in the fire, what was on loan to friends, and what was stored in other locations.
I have been using librarian pro for a very long time. As a clergywoman I have an extensive library of books, both professional and personal. This is like having a card catalogue of my library at my fingertips. I am also able to see what I have of various collections so that I don't re-purchase what I already have.
Great program, use it already for many years to categorise my books. Would love to have a synchronisable app version for my iPhone or iPad.
Muito Bom
This isn't just an inventory system. It's an incredible one. Better than anything else I've ever used. Not only is it superior to Delicious Library in my opinion, it's also compatible with it - how can you argue with that? This app has saved me so much time and stress I feel the least I can do is write it a golden review. 10/10 and two thumbs up here for sure.
Its the best software for my library. Had quite a number of different programmes, but this one beats the rest.
Helps me to never duplicate a purchase again. Keeps all my favorite authors together. Very good program.
I am a Library and Information Technician and I love Librarian Pro to control my personal collections. It does what I need it to do.
I like the fact that it's a all in one software. Very easy to use and great layout. I plan on listing all my books and all other media. thanks for a great product.
Delicious Library really limits what you can do with it once you've actually put a collection into the database. Librarian Pro has no limits whatsoever. I think I've officially been converted… so long, Delicious. It's been fun.
