Portico——一种电子期刊存档模式

Portico于2005年成型并启动。此计划主要是保存电子形式的学术文献，通过对典藏电子资源开展收费模式的经营，建立长久的典藏机制。Portico的电子期刊归档方案是针对出版商电子资源文档的保存，其规范化文档工作重点在于确保资料未来的有效性和可索取性。目前，Portico的商业模式已经建立，而这种商业模式不但切中了图书馆的需求，而且也符合出版社的意愿。     

Cooperative Trends in Digital Archiving: An Open Discussion

In putting together the NASIG strategy session “Cooperative Trends in Digital Archiving,” the three panelists, Daviess Menefee (Elsevier), Eileen Fenton (Portico), and Marilyn Geller (Lesley University), discussed issues they faced in their own organizations. All three panelists shared concerns about the need for archiving in general and for archiving born digital journals specifically, and about core organizational values that led them to pursue digital archiving. They had common concerns about who should be involved in digital archiving projects and how it should be accomplished. There were some interesting parallels in the decision making process within each organization. In this presentation, each of the panelists discussed how and why they came to their decisions, and how they all relied on the CLIR report, E-Journal Archiving Metes and Bounds, ¹ 1.

Building a Social Compact for Preserving E-Journals

In the shift of scholarly publishing from the print environment to online, the preservation of the scholarly record has become more complex, difficult, and uncertain. Current efforts are not adequate. Core criteria and certification processes have been developed for digital preservation repositories. Broad library support is crucial to the sustainability of third-party preservation archives. Publisher participation in third-party archives has grown, but coverage is incomplete and uneven, leaving some categories of materials well-covered and others vulnerable. Preservation programs need to coordinate their efforts and view themselves as collaborators rather than competitors. The task of preserving the digital scholarly record cannot fall to libraries alone—it requires a social compact among all involved parties.     

LOCKSS还是Portico——谈图书馆电子资源的长期保存
