Digitalization of the main estate of the physiologist and physicist Hermann von Helmholtz (1821-1894) and retroconversion of the available finding aids

柏林-勃兰登堡科学与人文学院(BBAW)的档案可以追溯到17世纪，其中包含约6500米长的档案材料。这些藏品包括19世纪杰出的科学家和科学组织者赫尔曼·冯·赫姆霍尔茨的主要遗产，体积为5直线米。此外，慕尼黑的德国博物馆和柏林的西门子档案馆中的Helmholtz的部分遗产不超过0.3直线米。学院档案馆的个人文件包括关于生理学、病理学、光学、声学、电动力学、热力学、地球物理学和认识论的Helmholtz手稿和工作材料，以及他与Approx的科学通信。1700个字母。在2021年亥姆霍兹诞辰200周年之际，已经持续了几十年的个人文件的使用预计将会增加，随之而来的是对来源的数字化访问的需求。个人文件的编目始于1956年，最初是对通信文件的描述。在按时间顺序排列的信件索引中，每封信都分别注明了寄信人的姓名以及地点、日期和数量。1986年，这些信件根据通信伙伴的字母顺序进行分类，并用它们的数字和时间范围进行总结。此外，最初粗略列出的手稿和工作材料被更密集地编入索引。最后一步是打字的寻找助手，它于2007年被转换到Augias数据库中。然而，目前还不可能在网上提供这一检索辅助工具，因此在BBAW档案网站和德国档案馆个人文件中央数据库中只有关于这些藏品的一般信息。在DFG项目的框架内，根据惯例，非缩微胶片的个人文件将由项目工作人员在12个月内在现场兼职(每周20小时)进行数字化。反向转换的目的是合并Augias数据库中的通信索引和查找辅助工具，检查描述的所有细节，并在必要时更正和补充这些细节。用于近似的反向转换和集成。在对索引文件进行28,000次扫描后，我们申请了另一个项目工作人员职位，在公务员系统的高级档案员，为期13个月的兼职(每周20小时)。该项目的目的是通过档案门户-D在互联网上发布个人文件，这是德国数字图书馆的聚合器，一个单独的网站，和DFG查看器。通过将元数据整合到DFG项目CorresSearch中，通信将被置于一个更大的字母环境中，并将在项目目标之外进一步开发通信的可视化可能性。

The archive of the Berlin-Brandenburg Academy of Sciences and Humanities (BBAW) dates back to the 17th century and contains about 6,500 linear metres of archival material. The holdings include the main estate of the outstanding scientist and scientific organizer of the 19th century, Hermann von Helmholtz, with a volume of 5 linear metres. Further partial estates of Helmholtz in the Deutsche Museum in Munich and in the Siemens Archive in Berlin are no more extensive than 0.3 linear metres. The personal papers in the Academy Archive contain Helmholtz manuscripts and working materials on physiology, pathology, optics, acoustics, electrodynamics, thermodynamics, physics of the earth and epistemology as well as his scientific correspondence with approx. 1,700 letters. On the occasion of the 200th anniversary of Helmholtz in 2021, the use of the personal papers, which has been ongoing for decades, is expected to increase and with it the desire for digital access to sources.The cataloguing of the personal papers began in 1956 with the description of the correspondence files. In the chronologically ordered correspondence index, each letter was described individually with the name of the sender as well as the place, date and volume. In 1986 the letters were sorted alphabetically according to correspondence partners and summarized with their number and time extension. Furthermore the initially roughly listed manuscripts and working materials were more intensively indexed. The final step was a typewritten finding aid, which was converted into the Augias database in 2007. However, it has not yet been possible to make this finding aid available online, so that only general information on the holdings is available on the BBAW archive website and in the Central Database of Personal Papers of the Bundesarchiv. Within the framework of this DFG project, the non- microfilmed personal papers are to be digitized by a project staff member on site in 12 months part-time (20 hours per week) in accordance with the rules of practice. The aim of the retroconversion is to merge the correspondence index and the finding aid in the Augias database, to check all the details of the description and, if necessary, to correct and supplement them. For the retroconversion and the integration of the approx. 28,000 scans into the indexing files, we apply for a further project staff position for an archivist in the upper grade of the civil service with a duration of 13 months part-time (20 hours per week).The aim of the project is to publish the personal papers on the Internet via the Archive Portal-D, which is the aggregator for the German Digital Library, a separate website, and the DFG Viewer. By integrating the metadata into the DFG project correspSearch, correspondence will be placed in a larger letter context and further visualisation possibilities for the correspondence will be developed beyond the project objectives.
