First please check to see if you are qualified for this:
The rules they are are:
You must be 18 or older to apply online.
A Free Library card is available at no cost to anyone who lives, works, pays taxes, or goes to school in the City of Philadelphia. In addition, anyone who is 65 or older or who has a valid card with an Access PA sticker from another Pennsylvania library can obtain a Free Library card without charge.
Veterans and members of the Armed Services can also obtain a Free Library card without charge.
I have an access sticker in PA but I also am a Vet so I am qualified under both programs. They gave me the card under the Vet program.
I do NOT have to physically go to Philadelphia to get the card activated. I can do it online. This allows me to access their digital collection which includes ebooks, audio books and video.
If you are interested in audio books, I use the program sound taxi to convert. It costs 19 dollars but will convert audio to any form you need and also will remove the DRM so you can listen to it on your device.
