If publicly funded libraries (PFL) such as national libraries were to adopt a more open source approach when making digitized cultural heritage (CH) material available, users would be granted not only open access to delivery files at a surface level (in e.g. PDF, JPG, or XHTML) but ”deep access” to archival file material and technical documentation as well (such as TIFF, full XML/TEI, scripts, style sheets and machine instructions). PFL:s would thereby strengthen the force behind the values of equal access, of supporting education and research, and of distributing not only digitized material but competence and methods as well. They might also come one step closer to sharing information-rich material with other digitizing institutions by constructing valid banks of commonly and mutually accessible digitized CH material. As of yet however, this is far from the case. Many PFL:s are rather adopting a policy to restrict public access to light-weight delivery versions while charging users for access to the archival, deep level (or hiding it away altogether). This paper examines some of the arguments for such a restrictive policy and discusses feasible ways of bypassing some of the open source obstacles.
