These clearly written & easy to understand articles on data compression covered some basics I am familiar with:
- Compression can help save bandwidth & disk space - very important for those of us with limited computing power. Compression allows you to be a better steward of resources.
- In order for data compression to be successful, both the sender & receiver must understand how the information is encoded
- You probably won't be able to play WMA music files on some MP3 players - the files will have to be converted first.
- Lossless compression - original data can be retrieved
- Lossy compression - loses some of the data so it can be compressed, but the results are not the same as the original. This is like making a copy of copy - the more copies you make of the copy, the less it looks like the original.
Imaging Pittsburgh / Galloway
This article emphasizes the importance of collaboration, planning, metadata. I appreciated how he explained all of the challenges (metadata, selection, website) involved in this project & how they arrived at solutions that were accepted by all collaborators. The resulting website is impressive & demonstrates how important projects like these are to not only libraries & historical societies, but also to the public.
Youtube & Libraries / Webb
This article on using Youtube for library marketing, promotion, & instruction is pretty timely for me professionally. In the near future my web committee will be creating a Youtube channel to promote our career center's services, events, & tips on career planning. Youtube (in addition to Facebook) is probably one of the best ways to get the attention of our target undergraduate audience - it's free, the students use Youtube already, & there are relatively few administrative hoops we'd have to jump through.
