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米的档案材料。馆藏包括19世纪杰出科学家和科学组织者赫尔曼·冯·亥姆霍兹（Hermann von Helmholtz）的主要遗产，体积为5线性米。在慕尼黑的德意志博物馆和柏林的西门子档案馆中，亥姆霍兹的部分遗产不超过0.3线性米。学院档案中的个人文件包含亥姆霍兹的手稿和工作材料，涉及生理学，病理学，光学，声学，电动力学，热力学，地球物理学和认识论，以及他与大约。1700个字母。在2021年亥姆霍兹诞辰200周年之际，个人论文的使用已经持续了几十年，预计将会增加，对数字资源获取的渴望也将随之增加。个人文件的编目工作始于1956年对通信文件的描述。在按时间顺序排列的通信索引中，每封信都单独描述了发件人的姓名以及地点、日期和数量。1986年，这些信件按照通信伙伴的字母顺序排序，并总结了他们的数量和时间延伸。此外，最初大致列出的手稿和工作材料被更密集地编入索引。最后一步是打印出一份查找指南，并于2007年被转换成奥吉亚斯数据库。但是，目前还不可能在网上提供这种查找工具，因此只能在BBAW档案网站和联邦档案馆个人文件中央数据库中获得有关馆藏的一般信息。在DFG项目框架内，非缩微的个人文件将由一名项目工作人员根据惯例，在12个月内（每周20小时）在现场兼职进行数字化。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，并在必要时对其进行更正和补充。求逆变换和积分的近似。在查阅了28,000份索引文件后，我们又申请了一个高级公务员档案员的项目工作职位，兼职时间为13个月（每周20小时）。该项目的目的是通过Archive Portal-D在互联网上发布个人论文，Archive Portal-D是德国数字图书馆（一个单独的网站）和DFG Viewer的聚合器。通过将元数据集成到DFG项目通信中，通信将被放置在更大的字母上下文中，并且通信的进一步可视化可能性将超出项目目标。

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.
