Posted by Library Answer Person in : Uncategorized , add a commentcould you please tell us about the gem stone alexandrite
ANSWER PERSON RESPONDS: According to Encyclopedia Britannica (http://www.lib.duke.edu/databases/descriptions/britanni.htm), “Alexandrite is a remarkable and valued variety [of chrysoberyl] that when viewed along the different crystallographic (optical) axes, changes from columbine red to orange yellow to emerald green. In addition, the stone changes from green in daylight to red in artificial light.” It also says that “The two best known and most widely used varieties of chrysoberyl are alexandrite (transparent) and Oriental cat’s-eye (opaque). Because of its great power of absorption of certain colours, alexandrite looks green in daylight and reddish purple in artificial light. The cat’s-eye is a yellowish green colour and is characterized by a luminous line. The intensity of the light in this line varies according to the brightness of the rays of light that strike it.”
The International Colored Gemstone Association website has a more expansive entry (http://gemstone.org/alex.html).
Lilly library hours December 7, 2000
Posted by Library Answer Person in : Uncategorized , add a commentIt would be very benefitial if library hours for Friday and Saturday nights should be expanded to atleast midnight. Just because it is the weekend does not mean that students do not study. It is true that a majority of students do not study, but many students who care about their academics do. Moreover, many students do not have a quiet place to study, especially on weekends more than week days because many of their peers and dorm mates come back drunk and make a lot of noise and commotion. Even though east campus is technically a dry campus, this is not the case. It is ironical that in one of the best univerisities in the nation, devoted students have difficulties finding a place to study.
ANSWER PERSON RESPONDS: Lilly Library have discussed your suggestion, and have decided to collect use statistics to see if they can justify extending hours. There will be more on this later. Thanx!
Health Economics journal online December 4, 2000
Posted by Library Answer Person in : Uncategorized , add a commentThe journal _Health Economics_ published by Wiley is available online, but the catalog does not list it. Duke DOES have access:

Thanks.
ANSWER PERSON RESPONDS: This is a little complicated. The Medical Center Library has not finally decided to subscribe to this, and other, electronic journals from Wiley. Pending that decision, it is listed, temporary, only on their e-journals page (http://www.mc.duke.edu/mclibrary/respub/collections/ejrnl.html). If they decide to keep the subscriptions, they will catalog all the titles.
For more info, see Judy Woodburn (660-1140) at the Medical Center Library.
