    Description: International librarianship stems from a desire to bring about political change, transcultural understanding, collaboration, and mutual respect. Historically, librarians have been deeply involved with challenging issues of information sharing, equity in information access, and bridging the digital divide between different socioeconomic communities. This collection draws on case studies from American librarians who traveled to Central America, the Caribbean, Central Europe, Africa, the Mediterranean, and Asia to participate in librarian-initiated and sponsored projects. They united communities, promoted religious and cultural tolerance, developed new facilities, or enhanced existing libraries and archives, thereby enriching communities with resources, professional expertise, new partnerships, and sustainable development practices. 〈i>International Librarianship〈/i> offers insight into how these experiences might serve as templates and promote best practices in collaborations within the library profession in the United States and abroad, and it also demonstrates how international experiences can enliven home institutions upon return.

    Notes: Porous biodegradable poly(DL-lactic-co-glycolic acid) foams were seeded with rat marrow stromal cells and implanted into the rat mesentery to investigate in vivo bone formation at an ectopic site. Cells were seeded at a density of 6.83 × 105 cells/cm2 onto polymer foams having pore sizes ranging from either 150 to 300 or 500 to 710 μm and cultured for 7 days in vitro prior to implantation. The polymer/cell constructs were harvested after 1, 7, 28, or 49 days in vivo and processed for histology and gel permeation chromatography. Visual observation of hematoxylin and eosin-stained sections and von Kossa-stained sections revealed the formation of mineralized bonelike tissue in the constructs within 7 days postimplantation. Ingrowth of vascular tissue was also found adjacent to the islands of bone, supplying the necessary metabolic requirements to the newly formed tissue. Mineralization and bone tissue formation were investigated by histomorphometry. The average penetration depth of mineralized tissue in the construct ranged from 190 ± 50 μm for foams with 500-710-μm pores to 370 ± 160 μm for foams with 150-300-μm pores after 49 days in vivo. The mineralized bone volume per surface area and total bone volume per surface area had maximal values of 0.028 ± 0.021 mm (500-710-μm pore size, day 28) and 0.038 ± 0.024 mm (150-300-μm, day 28), respectively. As much as 11% of the foam volume penetrated by bone tissue was filled with mineralized tissue. No significant trends over time were observed for any of the measured values (penetration depth, bone volume/surface area, or percent mineralized bone volume). These results suggest the feasibility of bone formation by osteoblast transplantation in an orthotopic site where not only bone formation from transplanted cells but also ingrowth from adjacent bone may occur. © 1997 John Wiley & Sons, Inc.
