The following resources are ones that I personally recommend and are not a comprehensive list of available resources on this topic.

Sign with Robert (DVD and streaming, 10 volumes): This excellent series goes far beyond the usual introductions to American Sign Language (ASL) to create value for multiple audiences. Deaf actor and educator Robert DeMayo brings his native ASL fluency to the demonstrations of signs and discussion of culture, and the series features a clean visual style that keeps the focus on the language. The vocabulary segments go into far greater depth than most ASL materials, making the series valuable to advanced signers and interpreters as well as beginners.
Signing Savvy: This online video dictionary of signs is clear, accurate, and easy to use. Though the search function on the site is limited to subscribers, you can access as many signs as you want through the alphabetical index, or go to Google and search signing savvy + the term you are looking for.
Start ASL: This site offers three levels of free online ASL courses, as well as a fingerspelling course. Students download a free workbook in .pdf form and use it to work through the video activities in each unit. The free courses are quite robust, but the site also offers a more in-depth paid class option for those who want to access the courses free of advertisements, with the option to submit assignments for feedback and access additional material.
